ALARM FOR ONCOMING RESONANT WAVES Russian patent published in 2009 - IPC B06B1/20 

FIELD: physics; acoustics.

SUBSTANCE: present invention pertains to acoustics, particularly to devices for generating resonant acoustic oscillations in flowing liquid or gas medium, and can be used for making all types of high quality dispersion systems. The device comprises coaxially fitted cylindrical stator in form of a concentric acoustic resonator and hollow rotor, in the adjacent surfaces of which there are through openings, uniformly distributed around, an actuator for uniform rotation of the rotor, apparatus letting liquid or gas mixture into the rotor and product outlets. The hollow rotor of the alarm consists of a series of longitudinal sections with number of openings different by one from the number of openings of the stator for generation of progressive rotating resonant wave of oscillations in the resonator - straight, in the direction of rotation of the rotor, - if more by one and inversely, in the opposite direction of rotation of the rotor, - if less by one. The number of such sections of the rotor is arbitrary, and they alternate so as to provide for counter rotation of resonant propagating waves on adjacent borders of sections. All outlets are at a tangent to the outer surface of the stator in the direction corresponding to the rotary waves and are directed in the same transverse direction. That way, the alarm generates opposite resonant rotary waves, obtained from a single rotor.

EFFECT: increased output of the propellant with simultaneous increase of its efficiency, as well as simplification and reliability of the device
